My favorite choice would be either AliceJune or VivienneJune. I think I'd do Vivienne so that the girls have different initials, yet they are a little connected in that they both have a "V" in their name

moving to new account with username I like more... since we can't just change them

My favorites are Annalyse and Liliana. I like that Ava and Lily are both short and sweet names that age well. Annalyse is just so pretty and same first initials don't bother me that much (though I prefer to stay away from it).
